Profile extrusion technology supplier Greiner Extrusion of Nussbach, Austria, has a new innovation: Its flow.control pro using GESS.tronic, which brings together savings in material costs and reduced energy use.
Both products can be retrofitted to any existing calibration table, the company said. Greiner is offering a free two-week trial period.
The flow.control pro is used to speed up or slow down individual profile sections using hot and cold air. Fast and accurate flow correction gets applied, without affecting nearby sections. Material variations are compensated for inline.
In the GESS.tronic system, vacuum pumps for the dry calibrators are controlled by connected frequency transformers. A stable vacuum level is achieved through maintaining a constant water level in the manifold, and the strict separation of water and air.
